COLLAPSIBLE MEGAPHONE.

Application filed March 28, 1323. Serial No. 628,341.

To all to/mm it m e; concern Be it known that l, Anrriorl'v C. Wants, acitizen of the United States, residing at Racine, in the county ofRacine and State of l i isconsin, have invented certain new ant usefulImprovements in Collapsible Megaphones, of which the following is aspecification.

My said invention relates to collapsible 1O megaphone and it is anobject of the invention to provide a device of the character de scribedwhich can be folded easily and without damage and which can readily berestored to operative position. A further object of the invention is topro vide such a megaphone with a handle and with means for holding themegaphone firmly in open or operative position.

Referring to the accoi-npanying drawings which are made a part hereofand on which similar reference characters indicate similar parts,

Figure 1 is a side elevation partly in section of the megaphone incollapsed position,

Figure 2 is a plan of the same with parts broken away,

Figure 3 is a perspective of the megaphone in operative position, and

Figure 4 a perspective of the megaphone collapsed.

In the drawings reference character 10 indicates a mouthpiece,preferably of aluminum or other metal, which has a central openingsurrounded by an inturned central flange and an outer flange extendingover flat side members 11 at one end thereof and serving to hold theside members in open position as indicated at Figure 1. The side membersmay be made of indurated fiber, 40 cardboard or other like material. Theside members are connected by strips 12 of leather or other flexiblematerial preferably all located externally of the megaphone, for betterappearance, and are provided with 5 buttons 13, 14 and 15. A strap 16 issecured at one end by a rivet 17 to a side member 11. and at the otherend by rivet 18 to mouth piece 10. Between its ends the strap passesunder a guide 19 also secured to said side member. In the open positionof the megaphone a snap 20 engages the button 14; while a snap 21 on ashort strap secured to the flange of the mouthpiece at its opposite sideengages the button 15. In this way it will be seen that the parts of themegaphone are securely held together while the hand holding the strap 16will by reason of the guide 19 be prevented from disengaging the snap20. On the contrary the tendency is to pull the strap 16 and tighten thehold of the snap 20 on the button 141-.

In order to collapse the megaphone snaps 21 and 20 are released and theparts are folded in the relation shown in Figure l after which the strap16 is drawn taut and the mouth piece 10 is folded down on the oppositeside of the device bringing the snap 21 into position over the button 13to which it is secured. This holds the parts securely in the positionshown in gure lforming a flat package which can be placed in the pocketor other receptacle and be practically safe from injury. It will be seenthat either in the folded or half folded position the device mayconveniently be utilized as a fan, should it be desired to make such useof it.

While I have shown the device as flatsided, this being the mosteffective and durable, I do not limit myself thereto, as curved sidepieces may be desirable in some instances. The device shown in thedrawings and described in the specification may also. as will be obviousto those skilled in the art. be changed in other respects, by increasein the number of sides, and may be other wise modified without departingfrom the spirit of the invention. the true scope of which is shown inthe appended claims.

Having thus fully described my said invention, what I claim as new anddesire to secure by Letters Patents, is:

1. A collapsible megaphone com n'ising side members, hinges connectingthem at adjacent edges, a mouth piece having an an nular polygonalflange adapted to fit closely over the side members at one end thereof,and a circular flange adapted to fit into and tangentially contact theside members, said mouth piece holding the side members in openposition, and means to secure the mouth piece in place, substantially asset forth.

2. A collapsible megaphone comprising side members, a month piece havinga polygonal flange adapted to fit over said side members to hold them inopen position and a circular flange adapted to fit into and tangentiallycontact the side members, a strap secured to one of said side membersand to the mouth piece and serving as a handle tor the megaphone,substantially as set forth.

3. A collapsible megaphone comprising side members, a mouth piece havinga flange adapted to hold said side members in open position, a strapsecured to one of said side members and to the mouth piece and servingas a handle for the megaphone, means for fastening the strap to the sidemember closely adjacent the mouth piece and means at the opposite sideof the megaphone "for attaching the month piece releasably to said sidemember of the megaphone, substantially as set forth.

4:. A collapsible megaphone comprising flat side members, a month piecehaving a flange adapted to hold said side members in open position, astrap secured to one of said. side members and to the mouth piece andserving as a handle for the megaphone, a guide on said side memberadjacent the mouth piece and a button and snap located one on the strapand the other on the side member beneath it between the guide and themouth piece whereby tension on the handle portion of the strap serves tohold said snap in engagement, substantially set forth.

5. A collapsible megaphone comprising flat side members hinged togetherat their edges, a mouth piece adapted in one position to hold the sidemembers in open position, a strap secured to one side member and 'to themouth piece, a button on the opposite side piece, a. snap on themouthpiece adapted to be engaged over said button and a button on anintermediate side member over which said snap is adapted to engage inthe folded position of the megaphone, substantially as set forth.

6. A collapsible megaphone comprising flat. side members, a handlesecured to one side member and having a mouthpiece atlixed thereto, saidmouthpiece having an external polygonal flange: adapted to fit over theends of the side members and having an internal arcuate flange adaptedto tit into the ends of said members for cooperatively holding them inoperative position.

7. A collapsible megaphone comprising flat side members, a handlesecured to one side member and having a mouthpiece atiixed thereto, saidmouthpiece having an external polygonal flange adapted to fit over theends of the side members and having an internal arcuate flange adaptedto fit into the ends of said side members for cooperat-ively holdingthem in operative position, and means opposite said handle tor holdingsaid mouthpiece in position.

8. A collapsible me aphone comprising flat side members, a handle havingone end tired to one of said side members, and being longitudinallyslidably and releasably cured thereto adjacent its opposite end, amouthpiece secured to the last mentioned end of said handle, saidmouthpiece being adapted to tit over the ends of said side members.

9. A collapsible megaphone comprising flat side n'iembers, a handlehaving one end fixed to one of said side members and beinglongitudinally slidablv and releasably secured thereto adjacent itsopposite end, a mouthpiece secured to the last mentioned end ot saidhandle, said mouthpiece being adapted to lit. over the ends of said sidemembers, and means on said mouthpiece opposite said handle for holdingsaid mouthpiece in position.
